Abstract: Disclosed herein are related to a device controlling a wireless communication link based on an average amount of radiation exposure and quality of service (QoS). In one aspect, the device includes a processor configured to determine the QoS indicating a target performance of a communication link of a communication interface. In one aspect, the processor is configured to determine radio resource information of the communication link. In one aspect, the processor is configured to predict an amount of radiation exposure for a time period according to the QoS, the radio resource information, and the detected proximity of the user. In one aspect, the processor is configured to compare the predicted amount of radiation exposure for the time period against a time averaged threshold amount of radiation exposure. In one aspect, the processor is configured to allocate radio resources to the communication interface, according to the comparison.

Abstract: Described embodiments provide systems and methods for adjusting a radio usage of a wireless link according to a time-averaged specific absorption rate (SAR). A first device configured to concurrently maintain a first wireless link with a second device and a second wireless link with an access point of a network may determine a proposed radio usage of the first wireless link and the second wireless link. The first device may determine a state of the first device according to the proposed radio usage and sensor information from at least one sensor of the first device. The first device may determine a time-averaged SAR of a user due to the first device, according to a defined time window and the determined state of the first device, to adjust the proposed radio usage of the first wireless link and the second wireless link to satisfy a threshold level of the time-averaged SAR.

Abstract: A first device may include a processor, a first wireless network interface, and a second wireless network interface. The processor may be configured to, while associating with the access point over a first wireless network on a first channel via the first wireless network interface, establish a second wireless network via the second wireless network interface. A group of client devices including one or more client devices can join the second wireless network on the first channel via the second wireless network interface. The processor may be configured to receive, via the first wireless network interface, first information from the access point. The processor may be configured to send, via the second wireless network interface, the first information to the group of client devices.

Abstract: Methods of optimizing performance for a wearable device are described herein, as are systems and wearable devices for performing the methods. One example method includes selecting, based on first and second sensor data, a current position of a portion of a wearable device donned by a user relative to the user's body from among at least three predefined positions of the portion. The method further includes, after selecting the current position of the portion based on the first and second sensor data, determining whether to modify an operating characteristic of the wearable device based on the current position. The method further includes, in accordance with a determination that an operating characteristic should be modified based on the current position, modifying a first operating characteristic for a display subsystem of the wearable device or a second operating characteristic for a communication subsystem of the wearable device.
